Sweet stuff, but I think you could use a bit more contrast in your shading. It might be the scan doing it, but the lights should probably be lighter. A little fidgeting with the levels should do the trick.:)

Once again, I let my thread die for a number of years; and once again I apologize if the sudden resurrection irks anyone. I'm officially in art school, and thought I'd share some stuff here since not too many people irl (save for my wife) are all that interested. Simple stuff mostly, but with any luck it'll improve as time progresses.
